1. Middleton's bangs have never looked better. Their long-ish length helps frame her face and keeps the hairstyle from looking matronly. They sort of remind us of the way we used to leave out little tendrils from our prom updos back in the day. Except hers are infinitely chicer.

2. This is the ultimate day-to-night transition hair. Middleton kept the off-center part and sophisticated Bumpit-level volume from earlier in the day, but she pulled the rest of her hair back to create an intricate evening look that paired perfectly with her Jenny Packham gown.

3. The updo is intricate without being fussy. When you look up close, you can see the complicated loops and swirls that went into this hairstyle (we can only imagine how many bobby pins it took!), but the placement of the chignon—right at ear level, no higher—keeps it from looking overdone.

4. It looks good from every angle. Most hairstyles look good from the front, and some look great from the back, but not every updo photographs well from the sides too. Thanks to thoughtful details, like the piece of hair artfully wrapped around the top of the bun, this one does.
